The reason for this libqsql mismatch seems to be found in the point,that SL 11 KDE is still delivered with KDE 4.9.5.But this new akonadi-server is based on running under KDE 4.10, which is offered in Sabayon-Limbo repo. This version 1.9.0 it depends on 'libQtSql.so.4'.But (I don't know, how and why) akonadi slipped into upgrade stream for KDE 4.9.5, offered in Sabayon Weekly repo.I think, when KDE 4.10 is part of the distro (Daily Build) or KDE 4.9.5 is offered to be upgraded to 4.10 then akonadi server should work.But my question is, how to transfer my KDE-PIM data to the new KDE 4.10 PIM.Maybe I can export old and import that file into the new PIM.

Ryuno-ki....the second link didn't work, but if that's the adding the mysql flag I loathe to do that...I don't want to bork my system, I'll wait and see if the userbase server comes back up to see exactly what the recommendation is...

But it looks like if linuxfluesterer is correct I may just have to wait until KDE 4.10 is available...lxnay say patience...LOL...we shall see...
